Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable HVAC Cleaning Across Annapolis
HVAC cleaning in Annapolis typically costs $450-$1,400 for a full system, depending on what the camera shows inside your ductwork. Most jobs take 4-7 hours. We schedule within days, not weeks. If you’re in Eastport, Bay Ridge, or the Historic District and your air handler has been cycling humid Bay air for years, call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
CleanRun has worked in enough Annapolis crawl spaces to know what tidal humidity does to ductwork. That changes what we look for, how we clean, and what we put in writing. More on that below.
Why CleanRun Air Duct Cleaning Is Annapolis’s Preferred HVAC Cleaning Company
Annapolis homeowners ask for something specific: proof. Not a technician’s word that the ducts are clean, but a camera image showing the inside of every run before and after. We’ve delivered a documented photo record on every job since 2013, when Tomas Reyes started the company with a Rotobrush system and a simple rule: no claim that can’t be photographed or put in writing.
That rule matters more in Annapolis than almost anywhere in Maryland. A generic duct cleaning crew can vacuum a return plenum and call it done. In an Eastport rancher with tidal soil under the crawl space, that leaves active mold behind. Our HVAC Cleaning crews are trained to recognize the failure modes specific to this city: salt-air corrosion in exposed sheet metal, condensation inside uninsulated supply ducts, and mold colonization fed by 85-90% morning humidity off the Chesapeake.
Every technician who arrives at an Annapolis home is background-checked, uniformed, and identified by name before the door opens. That’s Haven Standard Clause 3, and it’s been in force since our first job. We don’t have a single decorational badge on this page because Tomas has never paid for one. What we have is a written price before work starts, a 365-Day Done Right Promise in writing, and photos you’ll actually keep.
Our HVAC Cleaning Services in Annapolis
HVAC cleaning in Annapolis isn’t one service. It’s a set of procedures that address different parts of the system, and in this climate some matter more than others. Here’s what we perform most often for Annapolis homes.
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler, where it chills the air passing over it. In Annapolis’s summer humidity, that coil runs wet constantly. Dust and biological growth bind to the wet surface, and within two or three seasons the coil is insulated by a fouling layer that forces your system to run longer to hit the same temperature. We photograph the coil before cleaning, remove the contamination with an EPA-registered coil treatment, and photograph it again. A typical coil cleaning in Annapolis runs $180-$420, often alongside an air handler cleaning.
Blower Cleaning
The blower wheel moves every cubic foot of air you breathe. When a blower wheel in Annapolis gets caked with particulates, it’s out of balance, which means lower airflow and a motor working harder than it should. We pull the blower assembly, remove the buildup, and verify the wheel spins true. If the blower was pulling damp air from a crushed flex run in a Bay Ridge split-level, we’ll document that too, because the blower cleaning alone won’t fix the underlying issue. Blower cleaning in Annapolis typically runs $150-$300.
Condenser Cleaning
The outdoor condenser coil faces the Chesapeake’s salt air directly. That’s the problem. Salt accelerates oxidation, and oxidized coils reject heat poorly. We clean condenser coils using a low-pressure wash designed to break down the salt film without bending fins. Homes along Spa Creek and Back Creek typically need this every 2-3 years, more often than inland counterparts. Expect $120-$250 for a condenser cleaning in Annapolis.
Air Handler Cleaning
This is the work that matters most in Annapolis’s older homes. The air handler is the cabinet where the blower, evaporator coil, and often the return plenum come together. In Historic District buildings retrofitted with central air decades after construction, the air handler is sometimes jammed into a joist bay or closet that was never designed for it. The inside becomes a collection point for dust, biological material, and anything pulled from damp return air. A full air handler cleaning in Annapolis runs $300-$650, and includes cleaning the return plenum, blower compartment, and coil housing, with photo documentation of each.

BeforeAfterTrusted Brands We Service in Annapolis
We work on systems built around Carrier, Trane, Lennox, Rheem, and Goodman, and we stock common filters, belts, and coil cleaners for each. Our equipment roster includes Rotobrush, Nikro, and Guardsman - professional-grade tools you can look up independently before you agree to a price. We don’t run vacuum cleaners you can rent from a hardware store into your ductwork. The difference shows up in the photos we hand you at the end of the job.
Common HVAC Cleaning Problems We See in Annapolis Homes
These are not generic warnings. They’re the specific conditions our crews document in Annapolis week after week.
- Mold colonization in supply plenums, fed by tidal moisture. In Eastport and Annapolis Neck, where crawl spaces sit over tidal, water-saturated soil, moisture wicks up into the mechanical space and feeds mold that spreads into the supply side of the duct system. Standard duct cleaning without sealing the return plenum and addressing the moisture source means the mold returns within a season.
- Disconnected or crushed flex duct in post-WWII waterfront ranchers. Flex duct runs through crawl spaces where it rarely gets inspected. When it crushes or disconnects, the air handler starts pulling damp, unfiltered crawl-space air directly into the supply side. The ducts might be clean, but the air isn’t.
- Pinhole corrosion in exposed sheet metal ductwork. Salt-laden air off the Chesapeake accelerates oxidation in exposed sheet metal, especially in attics around Spa Creek. These pinholes create duct leakage that pulls hot, humid attic air into the system, which then condenses inside the ductwork and creates new mold conditions.
- Historic district retrofits with inaccessible runs. Ductwork retrofitted into 18th- and 19th-century joist bays is often so cramped that clean-only crews physically cannot access the full run. They clean what they can reach and leave the rest. If a company doesn’t show you before and after photos of every run, ask why.
Pricing for HVAC Cleaning in Annapolis, MD
A full-system HVAC cleaning in Annapolis runs $450-$1,400. What moves the number is what the camera shows: how many runs there are, whether mold remediation is needed, whether flex duct is crushed and requires rerouting, and whether sealing work is required to prevent recurrence. Evaporator coil cleaning alone is $180-$420. Blower cleaning is $150-$300. Air handler cleaning is $300-$650. Condenser cleaning is $120-$250. We combine these into one written line-item price before work starts, under Haven Standard Clause 1, so you know the number before you say yes. Every job includes the Documented Photo Record: inside every run, before and after, delivered to you as part of the standard job record. Call (806) 606-6902 for a written estimate.

FAQs - HVAC Cleaning in Annapolis
Because the moisture source was never corrected. In Eastport, homes sit on a peninsula ringed by Spa Creek and Back Creek, and tidal soil keeps crawl spaces chronically damp. Moisture wicks up through the floor into the mechanical room, and a standard duct cleaning removes the mold but does nothing about the humidity feeding it. The fix is source removal under negative pressure with HEPA filtration, followed by sealing the return air plenum and correcting the moisture path. That’s what we document and warranty. Call (806) 606-6902 and we’ll explain exactly what we’d do in your home.
Yes. In most cases, we can access the full duct run through existing register openings, the air handler cabinet, and accessible plenum sections. The challenge is that many Historic District runs were retrofitted through 18th-century joist bays that are extremely cramped. Our technicians use extended-reach tools and, where necessary, small access ports in closets or other inconspicuous locations - never through original plaster unless you’ve already approved it in writing. Every access decision is documented before any work proceeds.
Salt accelerates oxidation in exposed sheet metal ductwork, especially in attics and crawl spaces. Over time this produces pinhole corrosion, which creates duct leakage. Leaking ducts pull in outside air - humid in summer, cold in winter - which then condenses inside the system and creates new conditions for mold. Homes along Spa Creek, Back Creek, and the Annapolis Neck shoreline show this pattern more than homes even 20 miles inland. Our condensers and exposed duct runs get inspected for it on every job.
If the blower wheel is caked with buildup, or the coil is coated with a layer that reduces airflow, cleaning the ducts alone won’t fix your air quality or your system’s efficiency. The air handler is where the air gets cold and gets pushed - if it’s contaminated there, every cubic foot of air passes over that contamination. Symptoms include faint musty odor when the system starts, longer run times, and dust buildup on registers shortly after cleaning. We photograph the inside of the air handler on every job and show you what’s there before and after.
Yes, and it matters more in Annapolis than in most cities because of the humidity. NADCA (National Air Duct Cleaners Association) standards define proper source-removal cleaning - removing contaminants at their source under negative pressure, not just vacuuming what’s easy to reach. For a waterfront home in Eastport or Bay Ridge, where mold and salt corrosion are baseline conditions, that standard is the difference between a cleaning that lasts and one that’s undone by next summer’s humidity. We follow NADCA procedures on every Annapolis job and include documentation of the work.
If you live in Annapolis, MD and your HVAC has been cycling Chesapeake humidity for years, you probably have questions a camera can answer. Call (806) 606-6902. We’ll give you a written price before anything gets taken apart, and photos of the inside of your system before and after. Annapolis is where we do some of our most technically demanding work, and the documentation is always part of the job.
